Hello,

Using Excel 2007

Pretty new at this.

I created a chart from three columns of data.
First column(A) has dates, the next two (B & C) has data.

The generated chart therefore has two linear curves on it.
The Horiz axis is the dates,
One curve is therefore dates vs Column B data
The other curve is dates vs C data.

Have a linear trendline on each.

No problems really, everything looks fine.

I have selected the data points to be filled in a Blue color.
And, they show up Blue. Great.

But on one of the curves, besides being filled with the blue color,
the circumference around each blue filled data point has a red color.

Tried deleting, and re-generating the curve, but it always shows up this
way.

The other curve show up with just the blue fill color, as one would
expect. No red circumferential outline.

Any idea as to why the red circumference around these data points which
have been filled in the blue color ?

Is it trying to signify something ?

Thanks,
Bob
